Ch 1357 - Add a new agent type for fixed targeting to Acquia Lift module

For now the agent type will only show up if you have the acquia_lift_target_enabled variable set to 1.
Ah, I had copied this from personalize_target's js and it doesn't support goals. We will be supporting goals in this agent plugin eventually but for now I'm just replacing this with a todo about that. For the debugger this is handled more centrally in personalize.js.
